What is the Comms Database?

The Comms Database contains the information necessary to
configure components in the comms stack.

Context

The Comms
Database has a set of parameters used to configure communications
on Symbian platform. The information stored in the Comms Database
is used to configure components in the comms stack. Information such
as connection preferences, account settings and some of the linkage
between components can be set in the comms stack. The configuration
data is stored in records in database tables. The data also has data
schema to define the tables. For more information and a full list
of the settings in the Comms Database, see the Reference

The Comms Database is configured in one of the following ways:

It is compiled
from a definition file into a binary file to ship in the ROM of a
device.

It is modified
from the original ROM version via runtime changes made through the
Comms Database (CommsDat) API. For more information about the CommsDat
API, see the Migrating from CommDb to the CommsDat API.
